Question

an angles of parallelogram is 40 degree more than its adjacent angle find the measure of all angles​

Answer 1

Step-by-step explanation:

In parallelogram

The opp. angles are equal

The sum of adjacent angles are 180 degree.

given, 1 angle is 40 more than the other

let the 2 angles be x and x+40

then their sum is

=>x+x+40=180

=>2x+40=180

=>2x=140

=>x=70 degree

So the 4 angles are

70,110,70,110 degrees

Answer 2

Answer:

let's the parallelogram be x and 2x+40

adjacent angle =180

dividing 180/2

=90

remove 20 from x because 2x+40we need

=90-20

x=70

2x=110
